Specification of Letters Patent.

Patented July 14, 1908.

i Application iled September 7, 1907. Serial No. 391,813.

To all whom it may concern:

Be it known that l, HARRY EMCKEOHNEY, of Rochester, in the county ofMonroe and State of New York, have invented a new and useful Improvementin Hose-Nozzles, which improvement is fully set forth in the -followingspecification and shown in the accom# panying drawings.

My invention is an im roved nozzle for hose, designed more particu arlyfor use with fire engines in the matter of extinguishing fires and forsimilar purposes.

One object among others in constructing this nozzle is to providemovable coacting parts so arranged that by shifting them a arge streamof water of the full capacity of the tip or nozzle proper may be thrown,or a slender stream of small diameter may be discharged through butindependent of the tip, a further shifting of the parts also serving toshut off the discharge of water altogether.

Other objects andA advantages of the invention will be brought out andmade to appear in the following description,.and the novel featurespointed out in the appended claims, reference being-had to theaccompanying drawing which, with the reference numerals marked thereon,form -a part of this specification.

In the drawing Figure 1 is a side view of my improved nozzle with partsshown in various positions by full and dotted lines. Fig. 2 is anelevation of parts at the middle of the device seen as indicated byarrow in Fig. 1, further showing the construction, parts being brokenaway. Fig. 3 is a view ooking into the end of the nozzle. Fig. 4 is atransverse section on the dotted line a in Fig. 5, small parts beingbroken away. Fig. 5 is a side elevation of the nozzle mainly in centrallongitudinal section, seen in the direction in which Fig. 1 is seen,parts bein lshown in two positions by full and dotte lines. Fig. 6 is atransverse section of inner parts on the dotted line b in Fig. 5. Fig. 71s an axial section of parts on the dotted ine in Fig. 6, parts beingbroken away. Fig. 8 is a plan of the base of the axial tube with the uper portion mainly broken away, the barrelp being in transverse sectionand the threaded ring broken away, a part at the left being horizontallysectioned on the dotted line c in Fig. 7 to uncover the ring of packing.Fig. 9 is a side elevation of the lower parts of the axial tube,detached, further showing the form, parts being broken away. Figs. 1

andV 2 are drawn to a scale smaller than that of the remaining figures.

Referring to the parts shown, 1 in the various figures is the main baseportion of the nozzle, internally threaded at its lower end to receivethe hose.

2 is the barrel of the nozzle held to have longitudinal motion in theupper end of the base 1.

3 is a cap threaded upon the upper end of the base 1 and forming a covertherefor, holding a ring of packing, 4, Fig. 5, to insure a Water-tightjoint around the barrel 2. The cap 3 is formed with a hexagonalperiphery 5 for receiving a wrench to turn it, and a divided or branchedstandard 6, Figs. 1, 2, 4, and 5, at one side of the barrel 2 to whichis pivotally hung a U-shaped bail or lever 7, by means of a transversebolt 8 passing through the ends of the lever and the branches of thestandard, a sleeve 29 being placed between the branches. The lever 7 isformed with two opposite inwardly-projecting trunnions 9 9, Fig. 4,extending between two pair of transverse spaced ledges 10 10, Figs. 1, 4and 5, projecting from the sides of the barrel 2. By means of thisconstruction when the lever 7 is swung one way or the other on the pivotbolt 8 the barrel will be correspondingly moved longitudinally throughthe upper end of the main base piece 1, these movements of the lever andthe barrel being indicated by the dotted-line positions shown in Figs. 1and 5. The'barrel 2 is formed near its upper end with an enlarged part11 above which it is exteriorly threaded to receive the tip or nozzleproper 12.

Within the main base 1 is placed removably a circular rest or holder 13,Figs. 5, 6 and 7, crossing the axis of 4the base 1 and formed with aring 14 having its periphery threaded and inserted in a threaded seat 15in the base 1 above its lower end. This holder 13'has a centralbody-portion 16 connected with the ring 14 by radial ties 17 leavingspaces 18 for the Vpassage of the water through it into the base 1. Thecentral part 16 has a ilange 19 at its upper side forming a shallow cupfor holding a disk 20 of packing material upon which the lower open endof the barrel 2 may at times rest. This holder 13 has a central threadedstud 21, clearly shown in Fig. 7, for receiving an internally threadedcircular body 22 holding, as a base, a slender tube 23, said tube, thebarrel 2 and the main base 1 being coaxial. This inner stud 21, and anupper body portion 25 re` ceiving the lower end of the axial tube 23 andbeing connected with the part 24 by thin radial ties 26 with spaces 27between for the flow of water into the tube 23. The part 25 of theexpanded part or tube base 22 is larger in diameter than the bottom part24 and meets the inner surface of the barrel 2, a ring 28 of packingmaterial, Figs. 5, 7, 8 and 9, serving to render the joint water-tightbetween the base 22 and the inner surface of the barrel.

The tube base 22 is usually screwed rmly upon the stud 21 of the holder13 so that said base, the tube 23 and the holder 13 act as a singlepiece, being inserted into and removed from the main base piece 1 as asingle body. And in use the said parts, that is to say, the inner base22, the tube, the holder and the main base 1 are relatively motionlessWhile the lever 7 and the barrel 2 with the tip 12 may occupy any one ofthree different positions as may be necessary. That is to say, when thelever is in its lowest position, as appears in full lines in Figs. 1 and5, the inner end of the barrel 2 will press the packing disk 20, asclearly shown in Figs. 5 and 7, in which position no water can flowthrough or out of the nozzle, the latter being temporarily out ofaction. When the lever is at its upper position, shown by dotted linesin Figs. 1 and 5, the barrel and the tip 12 will be extendedv as shownby the dotted positions in the two figures, the lower end of the barrelbeing up dis* tant from the disk 20 and forming a full opening into andthrough the barrel and thus permitting a discharge of water of the fullcapacity of the exit opening of the tip 12. If, again, the lever bemoved to occupy the intermediate position, shown lowest in dotted linesin Fig. 1, the barrel will be only slightly raised trom the packing disk20, as shown by dotted lines in Fig. 9, and sucient to uncover theopenings 27 Figs. 7, 8 and 9, leading into the tube 23 but notsufficient to allow water to pass into the barrel. In this position ofthe parts a stream of water will flow out of the tube through butindependent of the tip 12, the latter being, for the time, idle, forwhile the barrel is in contact with the part 25 of the tube base 22 andthe ring of packing 2S no water can ilow into it and the tip 12, theonly stream issuing from the nozzle being that delivered through thetube 23. Thus by adjusting the lever 7 the outilowing water may bedirected through both the barrel and the tube 23, or through the axialtube 23 alone alternately, or wholly stopped.
